I've just discovered using
radeon-profile that my AMD Radeon R5 M330 is limited at 750MHz core/1000MHz memory on Ubuntu, but since that's too low (Core should be limited at 1030MHz) I want to increase the limit. I have tried some methods which include adding/modifying files in
/sys/class/drm/card1/device/, but even with root access (tried both
sudo and root terminal using
sudo su) it says permission denied. I haven't found any other methods.
I am not trying to overclock here because the OEM set the core clock speed for the GPU on Windows to 1030MHz, so I just want to set the limit on Ubuntu to what it's supposed to be.
TL;DR: How to change the clock speed limit for the core/memory of an AMD Radeon GPU?
Note: I'm using open-source driver
radeon with the
padoka PPA added.
